Treatment of gas obtd. by pressure gasification of fuel - via water bath in which gas is cooled, satd. with water, and subjected to partial dust extn.

摘要

Gas is pref. at 5-70 bars and 800-1600 degrees C., and is fed through a pipe ending in a bell immersed in a water bath. The bell possesses a row of outlet holes via which the gas is uniformly distributed in the water; and a guide tube is located above each outlet hole so the gas streams promote continuous circulation of the water. Hoods are located over each guide tube to prevent excessive bubbling of the water; and the water bath has an overflow for continuous removal of the water below an exit for the treated gas.
